TSB for Gen 1 "bucking"?

TSB for Gen 1 \"bucking\"?

Isnt there a TSB out for a simple to repair to help the Gen 1's habit of "bucking" at slow speeds? I know about synching the throttle bodies, but seems like I read its a TSB to insert a screw someone to also help with the problem. Does anyone know the TSB #? I'd like to get it done, but pretty sure my Dodge dealer will have no clue what im talking about without the TSB # for them to reference

Contact Tators Dodge. The Viper Wizard will help you out. If you occassionally re synch your throttle cables your problems will go away.

If your dealer enters your VIN in their system, it should show the TSB. Basically the TSB will cover installing screws to lock the cables in place once properly adjusted. You want to ensure both TB's fully open and that the drivers (TPS) side throttle body always opens first. The drivers side TB must always lead the passenger side TB.

It will help but will not totally stop the bucking

I have heard that it is best to just stick to resycing the throttle bodies periodically rather than going with the above fix. I believe that the explination was that as the heat in the engine bay causes parts to expand and contract slightly, the fix may actually just end up causing the throttles to be off slightly.

Re-synching took the problem away entirely for me!

Hi Chad,
If you put that screw in the adjusters like the TSB says you wont be able to adjust the cables anymore! On my 94 I adjust the cables 3 or 4 times in a driving season and that cures the bucking.

That's about every other month. Can't anyone come up with a better solution?

Re: TSB for Gen 1

like chuck said, if you have those screws, you can't sync the throttle bodies. I had them and just took them out. now I sync the throttle bodies anytime I think I need to. I have had the best results syncing the throttle bodies when the engine has been running for a while and is completely heat soaked.

next time I see you I can show you how to do it, very simple to do and makes a world of difference.

Re: TSB for Gen 1

I bought a set of GEN2 throttle bodies and throttle cable. Is it possible to convert the GEN1 setup to a GEN2 setup? I'm working everyday and haven't had the opportunity to try them out.

Re: TSB for Gen 1

I don't know why this is such a big deal. I think the genI design is superior because you can balance the throttle bodies. I have seen genII engines out of balance because of slop in the throttle system. it's so easy to balance these things.

Re: TSB for Gen 1

You can balance the Gen2 with a screw on the shaft. A single fixed shaft always better, the main reason is to assure that both throttles sync throughtout the range.

Re: TSB for Gen 1

The left throttle body leading the right one, is this applicable to Gen II's as well? I have been experiencing some bucking lately as well.

Yes, Gen I & II

Can you provide a little more detail on this for us idiots. My GenII has also been bucking at low speeds. First Ive heard about the GenIIs needing to have the throttles synced. Thanks.

Re: TSB for Gen 1

You have to be careful when you say left or right, it is as you sit in the car. The passenger side always should lead the drivers side. There is an adjuster screw on the passenger side. It will have a paint drop on the threads to show if it rotated.

Stand on the passenger side and reach over with your right hand to drivers side of the shaft and merely rotate the shaft. You can easily see which starts to open first, just make sure the passenger's side opens a little before the drivers.

"The passenger side always should lead the drivers side"

I'm 99% sure that the drivers side leads first, are you sure about this?

 

[Jack B]

Re: TSB for Gen 1

On the Gen 2, the passenger side leads the drivers side. The throttle position switch is on the passengers side, that is the reason.

I pulled out my 02 Service Manual because I was pretty sure I saw the TPS sensor on the drivers side. The description in the manual is as follows:

The TPS is mounted on the drivers side throttle body. The sensor connects to the throttle blade shaft. The TPS is a variable resistor that provides the Powertrain Control Module (PCM) with an input signal.

Devildog: I skimmed through the manual under the engine section, it recommends to replace the ignition cables when experience hesitation/misfiring under acceleration at low rpm's. I have 11K miles on my original wires, I will be changing out the MSD's soon. I also already had checked my throttle bodies not that long ago and they did not require adjustment. If the problem persists after new wires, some great tips were posted which I will use when re-checking the throttle bodies.

Ronnie:

now you have me thinking - early to rise and confirm. I can tell you this the factory setting on my 97 has the passenger opening before the drivers and there is no stumble

Re: TSB for Gen 1

Ronnie:

you are right, the TPS is on the left and the IAC is on the right - I stand corrected - thanks for the catch.

Re: TSB for Gen 1

ViperJohn...thanks I'll check out the ignition wires too.

Let me know what happens, you may get to replacing yours first!
